CHANGELOG

v0.8.0 (unreleased)

Features

  • major improvements to AppFactory and AppFactoryHook

    • support single-file app bundles (just export the app bundle as UNCHAINED_CONFIG)

    • support using a custom subclass of FlaskUnchained using AppFactory.APP_CLASS

    • support using a custom subclass of AppFactory

    • support passing all kwargs to Flask by setting the same names upper-cased in unchained_config

    • support automatic defaults for the Flask app kwargs root_path, template_folder, static_folder, and static_url_path

    • support using a custom module name for unchained_config by setting the UNCHAINED_CONFIG environment variable

    • make it possible to define multiple modules hooks should load from (excluding config and routes, as those only make sense to live inside a single module within bundles)

      • very experimental: add Bundle.default_load_from_module_name to ease migration from single-file app bundles to individual modules for different types (ie grouped by base class)

  • set up automatic dependency injection on commands (use from flask_unchained.cli import cli, click and define command groups for your commands using @cli.group())

  • add flask unchained config command for listing the current config (optionally filtered by bundle)

  • add flask unchained extensions command for listing extensions discovered by the app

  • add flask unchaiend services command for listing services discovered by the app

  • alias flask.abort (werkzeug.exceptions.abort) as flask_unchained.abort

  • alias flask_wtf.csrf.generate_csrf as flask_unchained.generate_csrf

  • alias flask.Request and flask.Response into flask_unchained

  • support Accept headers for handling responses in the API bundle

  • allow customizing the endpoint prefix for controllers using Controller.Meta.endpoint_prefix

General Improvements

  • document the rest of SQLAlchemy’s config options

  • automatically discover services in the services and managers modules of bundles

  • bump sqlalchemy-unchained to v0.11.0

  • add compatibility with pytest 5

Bug Fixes

  • fix grouping routes by which bundle they’re from

  • fix registration of resource method routes so the order is deterministic

  • fix ConfigureAppHook to load configs from every bundle in the hierarchy, not just the top-most one

  • fix passing explicit rule overrides to routes.resource

  • fix automatic endpoint names for resource routes using the default implementations for create/list/get/delete/patch/put

  • fix using default url rule from view function when no explicit rule passed to func

  • fix flask urls command when no URLs found

  • make sure hooks don’t resolve local proxies

  • fix ModelResource.Meta.url_prefix to use Meta.model.__name__ instead of the resource’s class name

  • allow using AnonymousUser as if it were a SQLAlchemy model in queries

Breaking Changes

  • rename flask_unchained.BaseService to flask_unchained.Service

  • rename PROJECT_ROOT to ROOT_PATH for consistency with upstream Flask

  • rename Bundle.folder to Bundle.root_path for consistency with Flask

  • rename Controller.Meta.template_folder_name to Controller.Meta.template_folder for consistency with Flask

  • AppFactory is now a Singleton that must be instantiated (ie change AppFactory.create_app(env) to AppFactory().create_app(env) in wsgi.py)

  • no longer automatically set up dependency injection on all the methods from classes (you can still decorate them manually with unchained.inject(), but the preferred approach is to use class attributes to define what to inject into classes)

  • default endpoint name for simple view functions is now just the function name

  • rename Resource method name constants to reduce confusion with HTTP method names

  • remove AppBundleConfig.ROOT_PATH and AppBundleConfig.APP_ROOT as they didn’t always work correctly (use BundleConfig.current_app.root_path instead)

  • moved flask_unchained.commands.utils.print_table to flask_unchained.cli.print_table

  • if using the API bundle, require marshmallow>=3.0, marshmallow-sqlalchemy>=0.23, and flask-marshmallow>=0.12

  • if using the SQLAlchemy bundle, require sqlalchemy-unchained>=0.10

  • CSRF protection is no longer enabled by default. To re-enable it:

from flask_unchained import AppBundle, BundleConfig, generate_csrf

class Config(BundleConfig):
    SECRET_KEY = 'some-secret-key'
    WTF_CSRF_ENABLED = True

class TestConfig(Config):
    WTF_CSRF_ENABLED = False

class YourAppBundle(AppBundle):
    def after_init_app(self, app) -> None:
        @app.after_request
        def set_csrf_token_cookie(response):
            if response:
                response.set_cookie('csrf_token', generate_csrf())
            return response
  • customizing bundle module locations changed:

class YourBundle(Bundle):
    extensions_module_name = 'custom'  # before
    extensions_module_names = ['custom']  # after

    services_module_name = 'custom'  # before
    services_module_names = ['custom']  # after

    commands_module_name = 'custom'  # before
    commands_module_names = ['custom']  # after

    blueprints_module_name = 'custom'  # before
    blueprints_module_names = ['custom']  # after

    models_module_name = 'custom'  # before
    models_module_names = ['custom']  # after

    admins_module_name = 'custom'  # before
    admins_module_names = ['custom']  # after

    resources_module_name = 'custom'  # before
    model_resources_module_names = ['custom']  # after

    serializers_module_name = 'custom'  # before
    model_serializers_module_names = ['custom']  # after

    celery_tasks_module_name = 'custom'  # before
    celery_tasks_module_names = ['custom']  # after

    graphene_queries_module_name = 'custom'  # before
    graphene_queries_module_names = ['custom']  # after

    graphene_mutations_module_name = 'custom'  # before
    graphene_mutations_module_names = ['custom']  # after

    graphene_types_module_name = 'custom'  # before
    graphene_types_module_names = ['custom']  # after
